I picked up this lens when I bought a Pentax Super M camera in a bundle.
It works opposite to what is expected as fully extended is lowest focal length.
Focus is very good, but becomes soft when wide open. Around F5.6 this is rectified
Good lens for Landscapes, no good for walk about lens

This lens is very sharp for it's cost - I believe sharper at some points than the kit lens, making it a very good replacement for the kit lens, as long as you don't have a problem with manual focusing. The lens is a push-pull zoom type, pushing will bring you to 35mm, and pulling to the shortest length gives you 75mm (a little counter intuitive).
Picture quality is quite good. There's some negative effects from taking pictures with too much sunlight, but I hope a hood will solve that.

| Pros: | Sharpness wide open, color | | Cons: | Aperture trouble | |
I got this lens for $30 after being impressed with a Ozunon 35-70 lens I used. After having received I checked it out against a F 35-70. At full length and the largest F stop (3.5 for the Ozunon vs. the F @ 4.5) it blew the normally sharp Pentex lens away. zoomed the images out to 14x and the UPC codes on boxes on my bookshelf were just so sharp with the Ozunon. This was more than 5mm length could explain away.
I tried other apertures but had exposure problems. Then I realized that the Ozunons aperture was stuck open. I managed to get it to close and could see through the front of the lens that the leaves of the aperture were just covered with oil.
If you can get one of these with a good aperture than I think you will like it, but be sure to look first. As for me I am trying to learn how to cleanup the one I have, because it promises so much.
I was able to get the aperture out. Soaked it in some isopropyl alcohol and it loosened right up. After reassembly it is working well. It is good glass though and I like the way it renders colors.
Also I have seen a Toyo Optics Five Star lens that appears to be exactly like this Ozunon lens. Likely they are the same maker. | | | | | Junior Member Registered: February, 2011 Location: California Posts: 32 | | Review Date: March 11, 2011 | Recommended | Price: $26.45

| Pros: | Color rendition, Build quality, Price | | Cons: | 70mm really?, A lock | |
A 'one touch 'mini-zoom' which I bought on E-Bay as "Vivitar". It did have a Vivitar lens cap on it. It appears to be of good quality construction and actually looks very nice. All controls are smooth operating and feel solid. Zoom works opposite of the way most do- longest focal length is with zoom ring back. Some Vivitars do have similar appearance.
Nice color appearance and sharpness drops only slightly at F3.5. I liked pictures from this lens from first shot. I have not had a chance to shoot in brightly lighted conditions yet but am confident it will only get better at higher F#.
Two criticisms- First compared to other zooms I have it looks like a 60 or 65 mm at long end. secondly the A position does not lock so the aperture can get moved without meaning to.

| Pros: | Surprising lens. Decent IQ and unique feel to photos | | Cons: | Focusing is budget although dampened | |
I picked this lens up at a pawn shop for $15. It's a surprising performer for that price.
It's got the one touch zoom/focus that seems to have been popular with lenses of this era. It's focus is dampened, but doesn't feel as solid as the Pentax M series lenses to be sure.
It's way sharper wide open than I expected. Obviously this is no DA*/FA* glass, but the few photos I've taken with it have been quite a surprise.
It always reports 3.5, even when zoomed when it should be 4.8, a side effect of it's age I expect.
An interesting thing about this lens is the second element from the front is a giant bubble. It looks as though this lens would be a fisheye, although that is obviously not the case.
The most unique thing about this lens is that it gives everything (especially highlights) a faint pink cast. I would think the auto correcting WB of my K-7 would remove it, but it's in most of the shots I've taken. It gives photos taken with this lens a unique characteristic that you may love or hate.
